Semi-Annual and Prompt Deviation Reporting Review of the Rules Semi-annual Reports 40 CFR 70.6(a)(3)(iii)(a) Each Title V Permit must require: Submittal of reports of any required monitoring at least every 6 months. All instances of deviations from permit requirements must be clearly identified in such reports. Prompt Deviation Reports 40 CFR 70.6(a)(3)(iii)(b) Each Prompt Deviation Reports 40 CFR 70.6(a)(3)(iii)(b) Each Title V Permit must require: Prompt reporting of deviations from permit requirements, including those attributable to upset conditions as defined in the permit, the probable cause of such deviations, and any corrective actions or preventive measures taken. The permitting authority shall define prompt in relation to the degree and type of deviation likely to occur and the applicable requirements. 7-day for > RQ or for deviations lasting longer than 7 days Semi-annual for remainder
1. Failure to Assert Upset Defense Upset Defense is Provided in LAC 33:III.507.J Affirmative defense to technology based (not air quality based) permit limits Must have reported per Ch. 39 Applies to any situation arising from sudden and reasonably unforeseeable events beyond the control of the o/o, including acts of God Does not include noncompliance to the extent caused by improper design, lack of maintenance, operator error, careless or improper operation Any Ch. 39 report where one says not preventable should also say this was an upset per LAC 33:III.507.J This applies to both 7 day and semiannual deviation reports Upset defense should be asserted in every report Use it or Lose It!
2. Incorporating By Reference When Underlying Report Does Not Meet Deviation Reporting Requirements NSPS/NESHAP Excess Emissions Reports Identification of CEMS downtime not due to calibration Deviation or not? Does it matter if below or above the 5% of operating time per reporting period for more detailed reports? Identification of periods of excess opacity or excess emissions not due to SSM - Does it matter if below or above the 1% threshold for more detailed reports? Summary reports do not show probable cause of deviation or preventive/corrective measures LDAR Reports May identify deviations such as failure to repair w/in 15 days or failure to monitor certain components timely, or addition of new, not previously identified components Does not generally state probable cause of deviation or preventive/corrective measures
3. Failure to Identify As Deviations Matters Included in Underlying Reports Not Incorporated By Reference Need to review all other reports required by permit to ensure that there are not matters which could be defined as a deviation A deviation is not always a violation CEMs monitor downtime for other than required QA/QC Excused excursions are deviations but should clearly state that they are excused excursions Example: HON allows 1 excursion from an operating parameter limit per semiannual period for each control device Example: Combustor MACT allows 10 CO rolling average excursions each 60 day period, for certain types of events Example: Some CAM Plans have specified excused excursions
4. Improperly Using the Reconciliation Defense LAC 33:III.501.C.12 Emission estimation methods set forth in the Compilation of Air Pollution Emission Factors (AP-42) and other department-accepted estimation methods may be promulgated or revised. As a result of new or revised AP-42 emission factors and/or department-accepted estimation methods, changes in calculated emissions may occur. Changes in reported emission levels as required by LAC 33:III.919.B.2.a due solely to revised AP-42 emission factors or other department-accepted estimation methods do not constitute violations of the air permit; however, the department may evaluate changes in emissions on a case-by-case basis, including but not limited to, assessing compliance with other applicable Louisiana ar quality regulations. This does not apply to calculation errors only changes in the AP-42 factors or other LDEQ approved estimation method. When do you have a department-accepted estimation method?
5. Imprecise Reporting of Emission Limit Deviations Emission Limits generally are stated in Tons Per Year Average lb/hr Maximum lb/hr Do not simply state that the lb/hr was exceeded should state maximum or average If the tpy was exceeded, there almost always is an average lb/hr exceedance as well To Avoid double counting say exceeded tpy and corresponding avgerage lb/hr
6. Identification of Duration of Deviation Guidance indicates duration should be stated, but 70.6 rule does not really state that this is required (Ch. 39 does) Don t overestimate by speculating Some reports show duration as the entire duration of the reporting period where they do not know Better practice is to state date of discovery (clearly indicating that is date of discovery) and date of cessation Note: Have started seeing this on some open-ended line deviations (date found/date fixed)
7. Not Adequately Describing Corrective Action This is a basic requirement and must be stated for the report to be complete DO NOT leave blank or state No Information Provided Even though space is limited, this should be a relatively robust description (avoiding acronyms unique to the plant i.e. repaired the T84VX ) It is a public document on EDMS so should be something you would want the public to see LDEQ will use this description when evaluating enforcement action
8. Not Covering RMP and Part 82 (Refrigerants) Risk Management Plan Requirements Incorporation of Part 68 generically means all requirements are incorporated Some permits only incorporate specific sections of Part 68 Certify only what is in the permit itself Stratospheric ozone rules 40 CFR Part 82 Almost all facilities have at least comfort cooling units for control rooms subject to the rule and many have larger industrial units The fact that a contractor services does not eliminate need for deviation reporting/certification Common failures include failure to have all technicians who may open equipment certified, failure to use certified recycling/recovery equipment, not determining leak rate appropriately
9. Including State-Only Requirements Not Requiring Deviation Reporting/Certification The only state-only requirements subject to deviation reporting are emission limits (i.e., state-only MRR deviations or work practice standards do not require self-reporting) By law, all conditions of a Title V permit are presumed to be federally applicable unless they are specifically identified in the permit as being state only State-only conditions include: Any marked with a footnote in Table 1 of the permit identifying as state only typically Ch. 51 requirements Limitations in the State General Conditions are state-only including GC 17 HAP/TAP limits in the emission rate sheets that are not clearly marked as state-only are federal (even a TAP that is not a HAP)
Annual Compliance Certification Review of Rule 40 CFR 70.6(c)(5) - The annual compliance certification must include all of the following but may cross-reference the permit or previous reports : (a)the identification of each term or condition of the permit ; (b)the identification of the method(s) or other means used by the owner or operator for determining the compliance status with each term and condition during the certification period. Such methods and other means shall include, at a minimum, [the MRR specified in the permit]; (c)the status of compliance with the terms and conditions, including whether compliance during the period was continuous or intermittent. The certification shall be based on the method or means [designated in the MRR requirements of the permit.] The certification shall identify each deviation and take it into account in the compliance certification. The certification shall also identify as possible exceptions to compliance any periods during which compliance is required and in which an excursion or exceedance as defined under Part 64 of this chapter occurred; and (d)such other facts as the permitting authority may require to determine the compliance status of the source.
10. Not Identifying Means by Which Compliance Status Determined Where MRR Is Missing Must use all specified federal MRR Where MRR is missing must indicate how compliance was determined to be continuous Example: scrubber flow required to be monitored continuously, but scrubber flow meter was down for a day If you have an SOP that says you will visually monitor flow when meter down, you would identify this on the annual compliance certification Where there is no MRR specified such as for emission limitations Should describe how you know you met limitations For example: Review of operating rates was consistent with permit application emission estimation methodology Where there is credible evidence outside of MRR Not required to state this was relied upon if all MRR was conducted Cannot ignore credible evidence that is contrary to the MRR must at least discuss it
